Australia head towards victory

Australia dismissed overnight batsmen Jacques Kallis and AB de Villiers inside the first hour as they moved closer to victory on the fifth day of the second Test against South Africa at Kingsmead Tuesday.

South Africa were 307 for six at lunch, with Australia breaking through to the tail when JP Duminy was caught behind shortly before the interval.

The first of the tailenders, Paul Harris, was caught at deep midwicket off part-time spinner Simon Katich in the last over before lunch.

Mark Boucher was the last recognised batsman, with captain Graeme Smith not expected to bat because of a broken bone in his right hand.

A win for Australia would clinch the three-match series after they won the first Test in Johannesburg by 162 runs.

Kallis and De Villiers made their third wicket stand worth 187 before Kallis was caught at second slip off Mitchell Johnson in the sixth over of the day for 93.

Kallis added just five runs after being dropped by Michael Clarke at point off Ben Hilfenhaus in the previous over.

Three overs later De Villiers was caught behind in Peter Siddle's first over of the day for 84.

With no chance of chasing down a target of 546, Duminy and Boucher resisted for an hour until Duminy was caught behind for 17, gloving a vicious lifter from Hilfenhaus.

Australia took the new ball which was due when South Africa resumed at 244 for two at the start of the day.
